ToV all'wlzo'nz't may concern:

l Be it-lrnown that 'LJOHN A. MATTsoN, a citizen of Sweden, residinv atChicago, .in thegcount'y of Cook andj tateI of Illinois, have inventedcertain new and'useiul Improvementsfin vRoof Carriages, of which thevfollowing is a specification. Y

This invention relates to improvements in roof carriages'and its chiefobject 1s to provide a carriage adapted to travel over inclined buildingroofs to carry building ma'- terial or other material from place toplace upon the roof, orrrom side to side, end to end of the roof,etc.The carriageis so constructed and assembled as to permit its adjustmentto Vsuit roofs of various inclinations or pitches and to permit itsadjustment in other ways,- to be hereinafter set forth, to suit thegeneral lay of the roof. lVithl the foregoing and other objects in viewthe invention consists in the combination and arrangement of parts to behereinafter fully described, pointed out in the appended claims andillustrated in the accompanying drawings which form a part of thisspeciication and in which- Fig. 1 is a Jfront view of my improved roofVcarriage illustrating its application.

Fig. 2 is a side view of Fig. V1.

Fig. 3 is a top plan view of Fig. 1.

Fig. 4 is an enlarged plan view of the carriage itself. Y

Fig. 5 is a side View of Fig. 4, partly in section, the sectionedportion beingtaken on line 5.-5 of Fig. 4:..

Like reference characters denote corresponding parts throughout theseveral views. i

The reference numeral 1V denotes inclined 40.77roof beams transverselyof which the channel beams 2 extend.' Y `My roof carriage is adaptedtotravel over the roof upon the channel beams 2. The carriage comprises anouter -main- Jframe 3 substantially Vf shaped, the closed end of theframe being olfset; The sides of the frame 3 are formed with thelongitudinal slots 4 through which the set screws -extend thatadjustably con- -nect the upper ends of the brace bars 6 to said frame,the lower ends of said bars G being connected by set screws 7 to thelower sections 8`of the legs 8, 9, said leg sections telescopingone intothe other and being adjustably connected together by set Specificationof Letters'Patent. `.Patented APL Application filed December 11, 1918.Seria1'No.266,288.g

screws l0, the upper leg-sections .9 directly supporting the openrend of.the frameY 3.4 The lower-legsections- 8 are directly bolted shapedcasting 1-1 formed with a longito and supported by an' elongatedlink-fftudinal central slot 12, saidl casting in the ends of itslongitudinally :slotted portion beingp'rovided with the llangedwheels'13 adapted to run overthe channel beams 2.H

Adjacent each wheel 13 apiyot-11is carried by the casting` 11 and uponsaid pivotan.- i

angle pieceV 15 is carried whichV extends be-.

low the flange of the'l whe'el'13'Y and is disposed upon the oppositesidel of the beam 2 with respect to the wheel' flange. The purpose ofthe said angle piece'is to` prevent the wheel riding off the beam. Theangle shownY in full lines, Fig. 2, to its position shownin dottedLlines to acco-mmodate the to a slidingv auxiliary frame-18, said frame18 in its sliding movement moving the bolts 21, 22 back and 'forth intheslotted portions spectively, in said slots connect the runway 19, 2Oofthe runwayt The runwayat one end is connected directly tothesidesofthe frame3 and at its outer end it is supportedl f by the inclinedbraces 165V which run Atothe link 11. The bolts 22 carry acasting 23which extends transversely of the auxiliaryV frame' and which isconnected to one end ofY saidvframe by the axis 211 of a lianged wheel f25 adaptedlto run upon the channel beams 2. The purpose Yof. the slidingauxiliary@75d`YY` VV frame 18 is to adjust the wheel 25relatively:

to the wheels13 to permit the carriage to 'travel over channel'beams2of'varying distances apart. VTo the end fof. the ,auxiliary frameadjacent the wheel 25 I -secure an angular guard 26 which projectsbelowthe flange ofthe wheel into close proximity'to the channel beam andserves'to yprevent the wheelv from riding oli' the beam. The

guards 15, 26 cooperate with each other to retain lthe wheels upon thebeams 2 and 70 piece 15 may be moved Afrom its position Y l guard l5 maybe moved into dotted position, Fig. 2, to accommodate beamsv 2 having!wi de `treads.

The frame 3 is kept level regardless ot' the relative differences inheight of the beains 2 over which the carriage is running by means oftlie telescoping legs 8, 9 which, obviouslyJ are readily adjusted toraise or lower the open end of the frame. The material to betransportediupon the carriage is placed directly upon the frames 3, 18,or either of them, and the' carriage then manually pushed along the roofby one or two menV Who Walk upon the roof beams balancing` themselves bymeans of the carriage. The Work carriedY may be piled vagainst the arms27 lsupported by the braces 28 which adjustably secure them tothe frame3 as shown;

Vhatis claimed is z*- l; In a carriage, a V-shaped frame, legsadjustably supporting the open end of said rame, a Wheeled carrier forsaid legs, a`
